长信号变点检测

Long signal change-point detection

Gérard Biau, Kevin Bleakley, David Mason

摘要:

空间或时间有序数据序列中的变点检测是遗传学和金融等领域的一个重要问题。我们得出的渐近分布的统计最近建议检测变点。模拟其估计的极限分布导致一个新的和计算效率高的变点检测算法,它可以用于非常长的信号。我们通过模拟和以前基准的真实世界的数据集评估算法。

英文摘要:

The detection of change-points in a spatially or time ordered data sequence is an important problem in many fields such as genetics and finance. We derive the asymptotic distribution of a statistic recently suggested for detecting change-points. Simulation of its estimated limit distribution leads to a new and computationally efficient change-point detection algorithm, which can be used on very long signals. We assess the algorithm via simulations and on previously benchmarked real-world data sets.
